I’m looking for a way to create a Smart Playlist in iTunes that contains only songs without lyrics.
Or to be more specific, I want to be able to create a Smart Playlist of songs that I haven’t put through Get Lyrical and then run it though the app so that it gets lyrics for the songs that I don’t already have lyrics for.
I’m using iTunes 10.6.3 (25) on a mid 2010 MacBook running Mountain Lion.

Hey, thanks a lot. I haven’t actually used apple scripts before, but I went ahead and put you suggestion through AppleScript Editor and ran it, and it worked great. I have a question though. Is there a way to make it so that the script only adds songs? like maybe add a property of {media kind: music}? Also, when I ran the script, iTunes was unresponsive and then AppleScript Editor came up with error “iTunes got an error: AppleEvent timed out.” number −1712 But it seemed to create the playlist and add songs to it just fine.

Unless there is some wacky way to accomplish this, I am fairly sure it is impossible. The smart playlists take certain aspects of a song, and use them to filter through your entire library, looking for matches. They do not check the lyrics.

However, if you were to somehow get your 'Get Lyrical' app to make a minor, consistent change to the song title, or to rate all non lyrical songs a particular rating, then this could be used to filter out only the songs you want.
